标题: 专题资料--------W83627HF开机流程
第一：南桥的3VSB一定要有，最多的就是由1117分压得到，打值如果中间脚（一般为输出）对地的话，99%为南桥坏。集成的网卡也需要3VSB，短路的情况比较少见。
第二：32.768的晶振要起振，可通过波形来判断。或者用万用表测量其两脚的压差，这个方法基本准确。

第四，   83627的61脚要有5VSB，如果没有，查ATX9PIN到83627的61脚的线路。第五，

S-ON开关上要有3。3或5V的电压，没有的话先查5VSB到

S-ON的线路。
看跳线帽是否有3V左右的电压，最好不要低于2V。如果没有，电池和打跳线帽中间的

IN，如果跳线中间的PIN打值对地短路，南桥挂。第六，    以条件都正常后，就可以触发了，就是短接PS-ON，懂了吧。83627的68PIN应有跳变，没有就查68PIN到PS-ON的线路

第七，   看67PIN是否有3。3V到0的跳变。注意了，3。3V在没触发之前就有，如果没有就可以挑开67PIN，量进南桥的这一端，如果有电压，直接换IO，如果没有，南桥挂。

有很多板 73脚始终高电平。如何解释。

作者: 断箭 时间: 2008-11-11 12:05
73脚一直为高电平，不跳变，说明南桥没有返回信号。
PS：一、原贴有些描述上的错误的地方，各位有心的朋友应能发现，不影响检修流程，所以不改了。
二、黑色字表示IO脚位，红字表示跳变顺序。

哈哈1年后自己来回答自己提的问题了。
73脚一直高电平是因为强行断电导致南桥没有保存好休眠状态。。。。
